UNITED STATES WILLIAM E. COOK, OF MINNEAPOLIS, MINNESOTA.

WINDOW-SASI-I HOLDER.

Specification of Letters Patent.

Application filed September 2, 1919. Serial No. 320,980.

To all whom it may concern:

Be it known that I, IVILLIAM E. Coon, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in \Vindow- Sash Holders, of which the following is a specification.

My invention relates to window sash holders and an object is to provide a springactuated holder adapted to be mounted between the sash and the window frame so that the sash will be held at any desired height by means of frictional engagement of Another ob]ect is to provide a device which will also prevent the window from rattling. Another a device which in addition to the two functions already mentioned will also constitute a weather strip for the window.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and the novel features embodied in my inventive idea will be particularly pointed out in the claims.

In the accompanying drawings,

which 7 illustrate the applicatlon of my invention in one form,

Figure 1 is a View in front elevation with a portion of the sash and window frame in section. Fig. 2 is a view in vertical section. Fig. 3 is a View in section on the line 3-3 of Fig. 1. Fig. 4 is a detail view in section showing a portion of the strip and one of the springs on an enlarged scale. Fig. 5 1s a View in section on the line 5-5 of Fig. 4. Fig. 6 is a view in perspective on an enlarged scale of a staple which'I employ. Fig. 7 is a cross-sectional view on an enlarged scale showing a staple driven into place in a window sash.

Referring to the drawings, 10 designates a lower window sash and 12 designates a window frame or jamb. Between one side of the sash and the adjacent portion of the frame is placed a metallic strip which has its two edges bent at right angles to form the two side portions 1 1 and 16 of the friction-engaging element 18, the latter being preferably slightly bowed outwardly as shown in Fig. 5 for engagement with the jamb. A number of curved springs 20 are secured to the portion 18, as by means of rivets 22 extending through the middle of the springs. In Fig. 1 three of these springs are shown secured to the strip but the number may be varied if desired. The edge of the sash is preferably recessed to receive the metallic strip and the attached springs and longitudinal grooves are provided into which the side portions 14: and 16 of the strip are adapted to fit. These grooves may be located at the longitudinal sides of the recess just mentioned. WVhen the strip is in place between the jamb and the edge of the sash the springs 20 are held under compression as shown in Fig. 1 and the strip is held for vertical sliding movement with the sash by suitable means such as staples 24 and 26 driven into the sash at the top and bottom of the strip. One of the staples such as 26 is shown in perspective. in Fig. 6 and in Fig. 7 is shown driven into place in the sash near the bottom thereof. It will be understood that a similar staple 24 is driven into the sash near the upper end thereof, as indicated in Figs. 1 and 2. The strip, therefore, is not rigidly held but the portion 18 is held in frictional engagement with the jamb on account of the tensioning of the springs 20. In Fig. 1 the upper sash is designated by the character 28, and it will be understood that this sash is also provided with a frictionholding device like that already described. If desired both sides of the sash may be provided with the friction-holding device.

The operation and advantages of my invention will be readily understood from the foregoing description. The portion 18 of the strip will be held by the springs in frictional engagement with the amb with sufficient force to cause the sash to remain in any position to which it is moved. The sash is thus kept at the desired height without the use of the customary cords and weights, and this provides a more economical and convenient construction. Since the sash is held firmly in place rattling is prevented. The device acts as a weather strip since a tight joint is made between the sash and the jamb c curing said strip to said to engage the customary window frame and having its edges bent substantially at right angles to the middle portion for cooperation with said recessed sash and for in-and-out movement relatively thereto, resilient members interposed between said middle portion of the strip and said sash, and means for sesash for longitudinal movement therewith.

2. In combination with a window sash which is longitudinally recessed on one of its sides, a U-shaped friction strip having its middle portion slightly bowed outwardly to engage the customary window frame and having its edges bent substantially at right angles to the middle portion for cooperation with said recessed sash and for in-and-out movement relatively thereto, resilient members interposed between said middle portion of the strip and said sash, and a U-shaped staple driven in the said sash at each end of said friction stripwhereby the latter is prevented from longitudinal movement relatively to said sash While permitting lateral movement of said strip.

In testimony whereof I hereunto affix my signature.

WILLIAM E. COOK.
